To all whom it may concern Beit known that I FRANCIS M. OSTEEN, acitizen of the United States, residing at Greenville, in the county ofGreenville and State of South Carolina, have invented certain new anduseful Improvements in Attachments for Pickers or Lappers, of which thefollowing is a specification.

turn feeds the fiberto the beater. With such a system there is a lack ofuniformity in the delivery of the fiber to the traveling apron, whichresults in the presence of thin spots or strips in the lap which is madeon this machine, such thin spots or strips resulting in the lapsplitting and tearing in the subsequent steps through which it ispassed. I

The object of my invention is to provide.

means located in the flue or feed chamber below the condenser and itsclearerroll and above the apron,such means consisting of an oscillatorymemberthat is moved in a horizontal plane at right angles to the path ofthe fiber, the range of "movement of the oscillatory or vibratory memberor rod being such as to cover the full width of the flue or feedchamber, such means in operation insuring an even distributionof thefiber over the apron which will result in the production of a lap inwhich there is an absence of thin spots or strips.

1 In the accompanying drawings which illustrate a preferred form of myinvention, Figure 1 is a side elevation of an accepted form of picker orlapper showing my improvement applied thereto. Fig. 2 is a plan view.Fig. 3 is an end elevation viewed from the direction of the arrow A,onFig. 1,

and Fig. 4 is a detail view.

The picking or lapping machine receives its supply of fiber through'thepipe 1, which discharges into a'chamber that contains a revolvingcondenser 52 from which thefiber is removed by a clearer roll 3, thefiber taking from the condenser falling or being deto a second condenserthat is within the casing 7 and from thence to calender rolls 8 leavingthe same in a continuous sheet of supposedly even thickness and of thefull width of the belt 4 and the condensers. After leaving the calenderrolls 8, the bat passes to the rolls 9 and is wound upon a mandrel 10 toform the roll or lap. In a device of the character above described inoperation any failure to start the fiber through the feed rolls 5 thefull width of the feed rolls and in a mass of even thickness results inuneven or thin places in the finished lap; for instance, should thefiber be deposited more on one side of the apron 4 than on the otherside the resulting sheet of fiber which forms the lap will be thin onone side and when the lap is later unwound in the further process ofmanufacture this thin place in the lap will break, causing what istechnically known as a split lap.

My invention is designed to eliminate uneven places in the lap and toprovide for an even deposit of the fiber upon the apron, and with suchend in view the shaft of the condenser 2 is provided with a pulley 12,that is engaged by a belt or band 13 which also engages a pulley 14 todrive a shaft maintained by abracket 15 which is attached to the trunkor casing in the upper part of which the condenser 2 is'mounted, and inthe lower part the apron 4:. The lower end of the shaft that is carriedby the bracket 15 has attached thereto a crank disk 16, having'therethrough a slot 16 through which is passed a bolt for connecting alink 17 with a rocker arm 18. The rocker arm 18 has a depending stud 18that is seated in a hearing block 19 which is clamped upon a rod 19 thatis suitably clamped to the trunk by eyeboltsand a rod on the oppositeside of the trunk from the rod 19*, which supporting means locates thebearing block 19 centrally with respect to the trunk, as shown in Fig.3. The rocker arm 18 is provided with apertured lugs and set screws forappropriately associating therewith a rod20 which extends through anopening 21 through the trunk 'to position the rod below the con denser 2and its clearer roll 3. The rod 20 may be bent as shown in Fig. 1 so asnot to engage the condenser 2 and the clearer roll 3 below which itoscillates or v'ibrates so as to intercept the fiber as it leaves thecondenser 2 and its clearer 3, preventing the fiber being deposited uponthe apron in a 7 mass at any one point and insuring an even distributionof the -fiber 7 over the entire wldth of the apron, so as to lnsureun1formity in the resultant lap. I

The oscillatory member or rod 20 may be adjusted upon the rocker arm18and by varying the point of attachment of the link '17 withthe crankor disk 16 the distance which the member or rod 20 moves may be variedto change the amplitude of the oscil-z lations, the oscillations beingpreferably in a I horizontal plane which is at right angles to the pathof thefiber on its way to the picker,

and'inopractice' it is desirable that the rod 20 and" parts associatedtherewith shall be ad-' justed so that the vibratory or oscillatory 1 7member shall have a range of movementequal to thefull width of the feedchamber or trunk The rod or member 20 is preferably bent so that itsmajor portion which is located inth'e trunk will be below the con-Vdenser and its clearer-roll, and by locating the downward extendingportion of therodbelow the clearer roll such bent rodrnot onlywhichofallsthereona Copies of this patent may be obtainedtor five centseach, by addressing- V wa sh'ingtomnacfi V clears the condenser butbeing inclined downward the rod will not retain the cotton The inventionhereinbefore described may be varied by duplicating the oscillatory rod7 or bar at different places in the trunk to en--' 'gage'the fiber as itgoes' fromthe condenser '2-and its clearer roll 3 to the feed apron'ofthe picker, and the invention is not only apfplicable to pickers orlappers but may be '6 applied to several types *or'f orms of carding-vmachinesthat form bats orlaps lclaimzry '1 7 V 1.
